Blistered Baby Zucchini, Baby Pattypan Squash, and Grilled Tomatoes

A pretty mix of Provençal vegetables, grilled simply and dressed up with the homemade basil aioli. You can also include other vegetables, such as halved baby beets, quartered bell peppers, and thickly sliced red new potatoes (all of which take 10 to 15 minutes to grill).
